IMPROVEMENT IN LUBRICATING SPINDLES.

Specilicatiou forming part of Letters Patent No. 165,433, dated July 13,1875; application filed April 14, 1875.

To all whom it may concern:

Be it known that I, AsEL M. WADE, of Lawrence, of the county of Essexand State of Massachusetts, have invented a new and useful Improvementin Mechanism for Spinning Yarn and do hereby declare the same to befully described in the following specification and represented in theaccompanying drawings, of whichy Figure l is a front elevation; Fig. 2,a longitudinal section; and Fig. 3, atransverse section of a spindle andbobbiu with sundry appliances appertaining to my invention, which' withthe said live spindle is shown a dead spindle,77 which is a single tubehaving a neck and shoulder to support the live spindle. It also has anoritice for discharge of the oil to and between the bearing-surfaces.

In such drawings, A is a tubular dead or stationary spindle, provided ator near its lower end with au oil cup or receiver, B, and also with ascrew, a, projecting down from said cup, in manner as shown. The cupcoustitutes a base to support the spindle on the rail C, with the screwt screwed into the coupling b of an oil conduit or tube, D, arrangedalong underneath the said rail C, in manner as represented. At theextremities of the conduit D are two stand-pipes, E and F, which extendupward abo-ve the top of the dead spindle. The pipe F terminates at topin an elbow-pipe, c, provided with a return-pipe, d, which extends downfrom the elbow-pipe to and through the spindle-rail G, and is providedwith a stop-cock, c, all being as shown. There is fixed to thespindle-rail, underneath the conduit D, a trough, G. Furthermore, the

hollow spindle opens at its foot, directly into the coupling b, andthere is an educt, f, leading through the bottom of the oil cup orreceiver B, and through the rail and into the y trough G. The deadspindle, at and near its upper end, is provided with a neck or journal,g, terminating at its foot iu a shoulder', h. lhere is a small hole oreduct, c', leading from the bore of the .tube througlrthe said journalor neck. A wooden tube or sleeve, H, encompasses the spindle, and takesa bearing, as shown, upon its neck g and shoulder h, and is held inplace thereon by the head of a screw, l, screwed into the upper end ofthe spindle. The Wooden tube H, at its lower part, is encompassed by atapering metallic tube, I, provided with a whirl, K, and there is driveninto the wooden tube, at its lower end, a tapering tubular bushing, L,whose otlice is not only to expand the wooden tube into so as to fit tothe tube I, but to serve as a bearing for the combined parts H I to runon the spindle. At its upper portion the tube H is slightly tapering, inorder that it, with the tapering part m ofthe tube I, may answer asfriction-bearin gs to a quill-bobbin, M, to encompass and tit to them,as shown. The bore of the tube H is somewhat larger in diameter than thespindle within it, in order that .oil escaping from the orifice 't' maypass freely down the outside of the dead spindle, and thence into thebearing-tube L, and from thence into the cup or receiver B, from whichit will be discharged by the educt thereof into the trough. If wesuppose oil from the trough to be thrown by a force-pump into the upperpart of the standpipe E, it will tlow down in such pipe into the conduitD, and thence up through the hollow spindle, out ot' which, by theelluct i, it will be discharged, so as to lubricate the bearingsurfacesot' the live and dead spindles, the surplus oil passing into thereceiver B, and from thence back into the trough. Any number of live anddead spindles so made may be applied to the conduit D, whereby theirbearing-surfaces may all be oiled. The auxiliary stand-pipe F and thereturn-pipe d, provided with the stop-cock e, are to maintain a properhead of oil on the dead spindle, and enable any excess of such oil to bethrown back into the trough. The stop-cock is to interrupt the escape ofthe oil, as may be necessary, to insure it being forced throughall thebearings, as Well as to cut olf the escape of oil, as circumstances mayrequire.

In the apparatus represented i n my Patent No. 153,185 the waste oilfrom the spindles passed into a chanuelin the rail, as the Waste oil inmy present apparatus escapes from the receiver B into the trough G; butthere was with such means of' discharging the oil nothing like theconnected stand-pipes F and d to maintain the necessary head of oil andalloW of the excess not required for lubrication to readily pass offinto the return channel or trough. v

1 do not claim the live spindle composed of the Wooden tube H, thctapering metallic bushing L, and the tapering bearing-tube I,

provided with the Whirl K. Nor do I claim,

in combination therewith, the single-tube dead spindle A, provided withthe bearing-neck g, shoulder h, and oil receiver or support B, as I havemade such the subject or subjects of claim in another applica-tion for apatent.

I claizn- The combination ot' the two stand-pipes E Fand the return-piped with the conduit D, and with a spinning-bobbin spindle or spindies,and the bearings or supports thereof, provided with one or more ducts toopen out of the conduit D and lead to and from the bearing-surfaces tobe lubricated, all being substantially as specilied.
